One of the main reasons capital needs labor to be fixed, so it can exploit wage gradients.
Closer and closer to a cyberpunk future every day lol.
There's outrage around taking jobs from locals in Toronto, but you could do that with fully automated ordering as well (I've run into this in multiple fast food settings in recent times!).
From my perspective, screen-based ordering from multiple kiosks with one or two cashiers is the only way forward, and although from a labour perspective it sucks for locals, it's almost definite that as the number of cashiers required goes down to below one per store, there will be a move to remote models with centralized resources (cashiers assigned to multiple stores) basically acting as intermediaries for the kiosks. It's not even a wage or working conditions issue, it's a labour requirement issue.
Assuming they can even find someone to fill the position.
I know from traveling around the states there is a significant problem in getting people to work in restaurants as they can just go down the street and get an entry level ‘career’.
